Heating device capable of uniform sealing

Abstract

The disclosure relates to a heating device capable of uniform sealing, uniformly applying heat at a constant temperature to the entire sealing portion of the to-be-sealed object to heat and seal the entire sealing portion at a constant temperature, thereby providing the uniform sealing thickness. A heating device capable of uniform sealing according to the disclosure comprises a heater for heating the sealing portion of the to-be-sealed object; a heat source supplier for supplying a heat source for heating to the heater; a heat transfer part accommodated in the heater, and transferring the heat source to the heater to heat the entire heater at a uniform temperature, and an additional heat transfer part disposed on the outer surface of the heat transfer part to conduct the heat source to the heater and in contact with the inner surface of the heater.

What is claimed is: 
     
         1 . A heating device capable of uniform sealing, comprising:
 a heater for heating the sealing portion of to-be-sealed object;   a heat source supplier for supplying a heat source for heating to the heater;   a heat transfer part accommodated in the heater and transferring the heat source to the heater to heat the entire heater at a uniform temperature; and   an additional heat transfer part disposed on the outer surface of the heat transfer part to conduct the heat source to the heater and in contact with the inner surface of the heater.   
     
     
         2 . The heating device of  claim 1 , wherein the heater is formed of nobinite or invar. 
     
     
         3 . The heating device of  claim 1 , wherein the heater is provided with a first accommodating space for accommodating the heat source supplier and a second accommodating space for accommodating the heat transfer part along the longitudinal direction. 
     
     
         4 . The heating device of  claim 3 , wherein the heater further comprises blocking parts for closing both ends of the second accommodating space, and
 wherein the blocking parts include at least one through-hole.   
     
     
         5 . The heating device of  claim 1 , wherein the heat transfer part is formed of a heat pipe. 
     
     
         6 . The heating device of  claim 1 , wherein the additional heat transfer part is formed of thermal grease.
